Like any transformer, current transformers have primary windings, core windings and secondary windings, although some transformers (including current transformers) use an air core.In principle, the only difference between a current transformer and a voltage transformer (common type) is that the former is supplied by a "constant" current while the latter is supplied by a "constant" voltage, where "constant" has a strictly theoretical significance for circuits.

The principle of a current transformer is based on the principle of electromagnetic induction.A current transformer consists of a closed core and winding.It's a little winding circle number, string in the current need to measure the line, so it often have all the current flows through the line, the secondary winding circle number is more, concatenated in measuring instrument and protection circuit, current transformer at work, its secondary loop is always closed, so the measuring instrument and protection circuit in series with the coil impedance is very small, the working state of the current transformer is close to a short circuit.

equipment,and to protect the equipment against the damage,in the AC circuit with the rated voltage value below 720V and the frequency of 50-60Hz.The product can be also applied to form a complete set of mine transformer. RCT have larger capacity. With the method of fixed installation.
